Bloqcode Chile – RUT and Checkout Validation adapts the native WooCommerce checkout process to comply with standard customer identification requirements in Chile.
Important Compatibility Note
⚠️ This plugin is designed to work with the Classic WooCommerce Checkout (using the [woocommerce_checkout] shortcode).
If your store is using the newer WooCommerce Checkout Block, you will need to replace that block on your Checkout page with a Shortcode block containing:
[woocommerce_checkout]
The plugin provides server-side and client-side validation to ensure checkout data structure correctness before payment processing. It formats the required metadata fields and organizes administrative information.
Features
- Field Injection: Inserts the RUT input field natively underneath customer first and last name fields within the billing section.
- Mathematical Validation: Runs validation queries based on the standard Modulus 11 algorithm on both frontend and backend handlers.
- Automated Formatting: Formats characters during user interaction to present standard punctuation patterns (e.g., 12.345.678-9).
- Order Metadata Panel: Appends stored billing RUT and custom delivery reference parameters directly inside the internal WooCommerce order edit screen.
- Email Layout Structuring: Restructures notification templates (customer and administrator copies) into separate Billing and Shipping data containers.
- Core Standards: Built strictly following WordPress API enqueuing requirements and WooCommerce filters.
